口腔囊虫病是链状绦虫的幼虫(囊尾蚴)寄生在人体颌面部组织内所引起的。口腔囊虫病常在人的舌、颊、唇、额、嚼肌、口底等部位发生,但以舌、颊处最为多见。其形态为色块状,包块较硬,大小不一,直径在2厘米内者为最多,包块位于皮下、粘膜或肌肉中,有的潜伏几个月,有的长达数年才被诊断发现。发病时有轻微疼痛、发痒和反复肿大症状,包块可单发也能多发,对人体健康和咀嚼机能有相当大的危害。囊虫病感染途径有三:一是体内自身感染。患有肠道链状绦虫病的病人,因恶心、呕吐或肠道逆蠕动,使绦虫卵返流至胃,再进入十二指肠,孵化成六钩蚴钻过肠壁,循血流至口腔及全身各部。二是 Oral cysticercosis is caused by the larvae of the tapeworm (cysticercus) parasitizing the human maxillofacial tissue. Oral cysticercosis often in human tongue, cheek, lip, forehead, chewing muscle, mouth and other parts of the mouth, but to the tongue, cheek most common. Its shape is colored lumps, hard mass, different sizes, the diameter of the largest within 2 cm, mass is located in the skin, mucous membranes or muscles, and some latent months, and some as long as a few years before Diagnosis found. When the onset of a slight pain, itching and repeated swelling symptoms, mass can be a single can also be multiple, on human health and chewing function has considerable harm. Cysticercosis infection has three ways: First, the body’s own infection. Patients with intestinal chain taeniasis, due to nausea, vomiting or intestinal peristalsis, the tapeworm egg reflux to the stomach, and then into the duodenum, hatch into six cysts through the intestinal wall, blood flow to Oral and systemic ministries. two is
